GT6 GT6 Bearing Q's

[Richter12x2]

Picked up a set of bearings for the GT6 that are .010 oversized for a machined crank. These are supposed to be for the early GT6 engines, but they don't appear to fit anywhere near correctly. The part #s on the box read VP856 010, and m4191 M/LC from Glacier, but this is the way they fit in the block. Any ideas?

The bearing I pulled out has a stamp 5106 on it, if it helps.

Googled the # and I get GT6

Me too. That's a GT6 engine though, and it was not impressed when I told it what Google said. :laugh:

Did you Google the bearing you pulled?

I didn't, but I found the difference. Apparently the very earliest of GT6's had a 2" main on the crank, and after KC5000 used a 2.3". That's the difference. Oh well, the bigger ones are cheaper anyway, I'll just have to see if I can find someone that needs a set of brand new early bearings.
